Pat, you might be getting into crazy territory there. Is that meant for stadium use?
And I thought my Blackbirds were loud …
Sorry I don't know of any manufactures of field coil drivers. I believe that field coil drivers were popular in the good old days. I heard that they are more expensive to make hence the lack of options and manufactures. I think the Focal uses a few in their higher end speakers. Many people claim they are sonically superior. Also the requirement to have an additional power supply complicates things. I found this online Field Coil - inSync.Have not considered it, and am don't expect that the distributors whom I trust vend any. I learned early on that BOTH the drivers and the supplier/distributor need to have the right qualities. Do you know of such a source? It maybe a fun thing to investigate.
On the subject of drivers, check out this set lined up for a Merlin prototype. Looks like Christmas morning to this kid. Each of these drivers is amazing. I've been getting used to the big-boys in one dual woofer mule, can barely wait for the second unit to join in. The unusually supple suspension apparently does good things for very LF resolution. The downside being that it's easier to bang the stops when there's very LF signal. I'm trying not to HP them, am aiming for solid performance into the teens. So, yep, as usual, add multiples 'til that limitation moves out of the picture.
An inspiration came, a few weeks back, by the sight of a shiny new racer on the St. Lawrence River with FIVE 450HP Mercury outboards crammed onto the transom. Most lunatics would have stopped at four, but not this guy. There's no way you'd get me on that thing - but he's my guy!

BTW do you have any distributers of your new speakers. Are you open to having people visit your shop to listen to some of your newest creations?
Thanks for asking. Most of our sales are made directly, and overwhelmingly to prior Meadowlark owners. Few of those guys even bring up the subject of an audition. We do have a talented reseller in the Atlanta area and we do enjoy giving auditions at the shop. We are in a remote location 90 miles N of Syracuse, 1000 Islands region.Sorry I don't know of any manufactures of field coil drivers.

Thanks Pat I am in the Toronto region. I visited you at your shop in Watertown many moons ago when you upgraded my Kestrels to hotrods. I need to plan a visit some time soon, I would love to hear your new line up.Thanks for asking. Most of our sales are made directly, and overwhelmingly to prior Meadowlark owners.

Yes, there's always beer.
No, no, no....that's nowhere near excessive. The engineering problems in the low bass are complicated by two adverse square functions that sum. It's not a 'common sense' kind of thing. What is practically necessary just looks nuts.Pat, you might be getting into crazy territory there. Is that meant for stadium use?

Ditto. Did someone say Havenite road trip?Thanks Pat I am in the Toronto region. I visited you at your shop in Watertown many moons ago when you upgraded my Kestrels to hotrods. I need to plan a visit some time soon, I would love to hear your new line up.
If you're not using all of the available output, you should lower the Input Level to suit. Reason: minimize bit dithering at your source.Pat, you might be getting into crazy territory there. Is that meant for stadium use?

Pat, I'd like to get your take on how you approach tweeter and mid range driver height in these designs that start getting taller. You still try to keep them at hear height?Prototype Ibis revision from a four-driver three-way to a five-driver four-way, heading to the shop floor, after nine CAD cycles. Objectives: break the cabinet into two modules, the large single cabinet Ibis V1 being an large and heavy pita in production. And, at the expense of needing another channel of amplification, for a total of five, bringing in the unbelievable Satori MR13P midrange.
Combined with one of two LF systems that will fit to the rear, will become Merlin seven-driver five-way or nine-driver five-way. The distinction will be the limits of what we've begun referring to as "bandwidth/amplitude", because one can select any point on the bandwidth/amplitude tradeoff limit curve. Some rooms need lots.
Design is always a bag of compromises, but I'm thinking we're giving up nothing on the big boys, it's a good feeling.
We've figured out a way to make Ibis V2 easily upfittable to either Merlin variant, by the customer, with just a screwdriver. And a few grunts, I suppose.

Ibis is intended as a mere 30 Hertzer. That 20-30Hz band is does require quite a bit more volume, hence the larger footprint.Really liking the Ibis V2 complement. I almost wish these were available when I got the Nightingales. The 13" wide Nightingale ended up being a bit more imposing than I anticipated in my space.
Yeah, you don't really want to be looking up into the soundstage. It's pleasing, though, to be looking straight ahead at it. Or, in the case of smaller speakers, slightly downward. The very popular Kestrel had its tweeter at 33" and guys really liked the presentation. Today, we're running Kingfisher, with tweeter at 37" and it's more than pleasant. The presentation of singer playing piano seems in scale and believable.Pat, I'd like to get your take on how you approach tweeter and mid range driver height in these designs that start getting taller. You still try to keep them at hear height?
Nothing like the smell of fresh cut mdf to get a project going.Ibis V2 / Merlin main array ready to glue. We redrew this eleven times before liking it enough to cut materials. I'm liking the feel of the scale and proportions.
